Wait, did Alex spoil something about 7 or about 6? Because if it's the latter, then I didn't notice.
he's spoiled a number of surprise reveals throughout the series.vin diesel's appearance in tokyo drift, letty "coming back to life", tokyo drift being in the future
I don't know, I'm usually pretty fussy about spoilers and maybe I just didn't pay close enough attention, but all of these reveals still worked for me and it seems like they did for Vinny and Dan as well. So far, Alex's commentary has not diminished my enjoyment of the series. I agree that it wouldn't hurt if he instead said "just keep watching" more often, though.
